Abstract

The invention features an offshore oil installation (1) comprising two mounting plates (6, 8) resting on the ocean bed, each mounting plate (6, 8) supporting a manifold (10; 10') connected at two ends with two respective terminal joining pieces of flexible pipe section (5, 7; 7, 9) fixed to the manifold (10; 10') substantially in the extension of each other, each manifold (10; 10') further comprising a flange for sealed joining with a pipe (12) coming from an underwater structure such as a wellhead (2; 3), the manifold (10; 10') of the two supporting plates (6; 8) being interconnected at one end by a flexible pipe section (7) and connected at the other end by two respective pipe sections (5, 9) to a surface extracting installation (4).

Dependent claims

An offshore oil extracting installation comprising a first and a second separated mounting plates, each mounting plate for resting on the ocean bed;

a first manifold supported to adjustably tilt on the first mounting plate and a second manifold supported to adjustably tilt on the second mounting plate;
each manifold having respective first and second ends;
a respective flange on each of the first and second manifolds for sealed connection to a respective pipe coming from an underwater structure, each flange having a longitudinal axis which extends in a direction in relation to the plate which direction is reorientable with the adjustment of the manifold;
a flexible first pipe section connected between the first ends of the first and second manifolds connecting the first and second manifolds;
respective second pipe sections each having a first end connected to the respective second end of one of the manifolds, and each second pipe section having a second end that is connectible to a surface extracting installation.
